The expected interarrival time between jobs to an emergency center in a hospital can be approximated with an exponential distribution with an average of 10 minutes. The expected service time is 8.4 minutes with a coefficient of variation of 1.4.

4.1. (10) Please find the estimated wait time using VUT estimation.

4.2. (14) 20% of the patient will be transferred from the emergency room to the heart center, where they will undergo more testing. There are 6 identical testing systems in the testing center in the hospital. The average testing time is 8.4 minutes. The coefficient of variation in arrival and in-service are the same as in the emergency room. Please find the wait time.

4.3. (5) What if there 5 testing centers?

4.4. (5) Please observe the results from the above and discuss the impact of a number of servers.
